Prevent Wood-Ingesting Insects and Wood Decay.

Rot, weather, insects, and fungi all pose a serious threat to your logs. Protect your investment—treat your logs first to make them last. Board Defense, a borate-based wood preservative, helps protect your log home from the costly damage caused by rot and insect infestation.

How much Board Defense do I need?

* One 20 lb. / 5 gal. pail will cover 2,000 – 2,500 sq. ft., depending on wood porosity.

* One 1 lb. jar will cover 70 – 120 sq. ft., depending on wood porosity.
